Feature request: Volume key binds clamp to not allow over/under 0-1

[JCR64]

Seen here originally in nzportable: nzp-team/nzportable#1003

The default binds volup inc volume 0.1 and voldown inc volume -0.1 allow you to reach volume levels that I don't think the user would want. This becomes particularly unwieldly as those buttons are also usually used for controlling the system volume. I can unbind the keys in my config anyhow but I thought it might be something worth considering. Thank you!
